The AI engine for short-form video

From one idea to a published Short  automatically.

ClipNest writes the script, scores the footage, voices it, renders a captioned vertical video, and publishes it to YouTube, TikTok and Instagram — while you do something else.

How it works

Five stages. Zero busywork.

Every ClipNest video flows through the same automated pipeline our backend runs for real — from a blank idea to a posted video.

  1. 01 · Idea

    Pick a topic

    Generate topic and video ideas with an LLM, scoped to your app's theme.

  2. 02 · Script

    Write the script

    A six-step AI writer drafts and critiques a tight, spoken-word script.

  3. 03 · Footage

    Find the footage

    CLIP scoring matches every line to the most visually relevant clip.

  4. 04 · Render

    Render the video

    A serverless engine composes a captioned 1080×1920 video with motion and music.

  5. 05 · Publish

    Publish & repeat

    Schedule to every platform — or let automation keep the queue full.

01 — Script

A screenwriting room, not a single prompt.

Most tools fire one prompt at a model and hope. ClipNest runs a six-step writing room that researches, structures, drafts and edits — so every script earns its 55 seconds.

The six steps
01

Classify

Reads your idea and picks the right mode — fact, explainer, story or concept.

02

Investigate

Gathers concrete material — facts, events, mechanisms — each rated for confidence.

03

Spine

Builds the outline: hook, beats and throughline, timed to about 55 seconds.

04

Draft

Writes the spoken script along the spine, tuned to the rhythm of speech.

05

Critique

An editor with deeper reasoning grades the draft against a rubric and rewrites until it passes.

06

Normalize

Finalizes for voiceover — numbers become words — and writes the title, description and tags.

Four ways to frame an idea

Factual

Records, lists and numbers — opens on a single startling fact.

Explainer

How and why — opens on a counter-intuitive result.

Narrative

People and events — drops you straight into the action.

Conceptual

One sharp, contrarian idea — and its concrete implication.

02 — Footage

Footage that actually matches the words.

ClipNest doesn't keyword-match. It scores how well each clip visually fits the line it'll play under — then fills any gap without ever leaving a blank frame.

CLIP visual scoring

OpenCLIP compares clip frames to each beat's meaning, calibrated on absolute similarity — not the luck of a search.

A deep, pooled library

Pexels and Pixabay are searched together, de-duplicated and cached for every beat.

A graceful fallback cascade

Weak match? It drops to a stock photo, then to an AI-generated still — never a gap.

Always fresh, any orientation

Anti-repeat rotation never shows a clip twice in a row, across portrait, landscape or square.

03 — Render

Rendered like a studio, not a slideshow.

A serverless engine composes every frame: cinematic motion, smart fitting, transitions, mood and burned-in captions — in one clean pass.

Slow, deliberate zoom keeps stills and clips alive.

Crossfade transitions

xfade between shots, micro-rendered in parallel and stitched losslessly.

Eight mood filters

Set the tone per clip — from vivid to dreamy.

Contain-and-blur fit

Any aspect ratio sits centered on its own blurred backdrop.

Speech-synced captions

Word-timed subtitles burned in, matched to the voiceover.

Voice + music mix

Voice at full, music ducked and faded out over the final seconds.

04 — Publish & Automate

Publish everywhere. Or never touch it again.

Send finished videos to every platform on a schedule — or hand the whole channel to automation and just watch the views.

YouTubeTikTokInstagram
Publishing

Timezone-aware scheduling

Per-day slots in your timezone, with natural jitter so posts never look robotic.

Built-in compliance

TikTok creator info, privacy level and brand-safety are handled before a post goes out.

Per-platform tracking

See exactly which videos went live, where, and why any failed.

Automation

Topic rotation

Round-robin, weighted or random — keep your themes varied automatically.

Queue targets & limits

Always keep N videos queued, with daily caps to control cost.

Never repeats itself

Title deduplication means it won't remake an idea it's already done.

Capabilities

Everything else you'd expect  and then some.

The pipeline is the headline. These make it a product.

Teams & roles

Invite collaborators as owner, admin, editor or viewer across app-scoped workspaces.

Realtime progress

Watch each stage stream live over Server-Sent Events — drafted, matched, rendered, published.

Music library

Per-app tracks with playback windows, mixed and faded under every video.

Any language

Generate content in any language, with speaking rates tuned per language.

Resumable by design

Every step is saved as an artifact, so a failed job retries from where it stopped — wasting no tokens.

Cloud storage

Finished MP4s land in your own cloud storage, ready to download or repurpose.
